Why High Quality CCTV Cameras Are a Must Have for the Home and Office


Some surveillance cameras are equipped with more and better functions than the ordinary, run of the mill surveillance cameras sold at a significantly cheaper price. There are no advantages to choosing a surveillance system unequipped with basic features and functions, not even saving money as it can cost you more in the long run in terms of burglaries.

A lot of people make the mistake of skipping the research stage before buying CCTV cameras or kits. They usually focus on price, not function. They do not assess their needs first and they do not scrutinize what is available in the market today. Here are some things that might happen if you buy a low quality surveillance camera...

1. The camera, when installed outdoors, might be prone to wear and tear.

Cameras installed on doors or windows of your home need to be extra durable to withstand rain, snow and direct sunshine. They need to be weather proof so as to not get damaged due to changing weather conditions throughout the year. Depending on where you live, you may even need to find a CCTV camera that can withstand minor hurricanes or regular thunderstorms. They should not be prone to rusting and they should still capture clear surveillance footage even during hot and humid seasons.

2. The camera might not capture images well under low light conditions.

Here is another mistake people make when buying. They tend to buy cameras that cannot capture clear images at night or during dark and dreary days. The camera you are buying should be reliable even under low light conditions. It should deliver a perfect image quality. Otherwise, it defeats the purpose of setting up CCTV equipment as most burglaries happen at night.

This is true especially if you are going to install it in your business establishment, when no one is in the building at night. Cameras with infrared sensors can be installed in parking spaces where lighting conditions are usually very low.

3. You might be buying a camera that is not backed by a warranty.

If you want to get the most out of the money you spent buying the CCTV camera, you should look for one that is backed by a warranty. In the unlikely event you experience problems with your camera caused by factory defect, if you do not have a warranty you will have to fork out for a repair or spare parts. Reputable brands will include a guarantee so you are covered in case of problems.

4. The camera might not have replacement parts.

If you are buying a cheap and unknown brand of CCTV, you might have a hard time finding replacements for some of the parts. Remember that there will eventually come a time when some of the parts with wear out and break down. The surveillance cameras you are using should have parts that are readily available in the market so you do not have to spend a lot of money replacing the whole system.

5. The camera you are buying might not be scalable.

It is important to look for a kit that can be expanded in the future. You may only want a small kit for now but if your car is stolen for example you may want to add an extension to have CCTV in the garage too. High quality cameras are designed to be compatible with other products from the same brand or even other brands, so you can adapt your CCTV system over time as your needs change.

It is more ideal to find high quality CCTV equipment. You can be assured that these products have been equipped with some of the most durable materials. They have passed rigorous tests and trials before being sold to the public. A good kit also comes with a warranty or a guarantee. If there are any defects, the company can replace it.

Companies selling these high quality surveillance cameras also have more options for you. You can choose from those with infrared sensors so the camera can still work even in low light conditions. They have parts that can be easily replaced.

Contrary to popular belief, high quality CCTV systems and kits are not very expensive. In fact, many companies selling CCTV equipment strive to give their consumers the best price without compromising the quality of the products. You need to find a CCTV camera with the right features for your own surveillance needs but you can find reliable cameras packed with intelligent features for a very reasonable price. The camera should have a very good resolution day and night. Make sure you check the features and compare them with other cameras you are thinking of buying so you can make an informed choice.

Cameras With Defective CCD's Can Be Fixed For Free!


If you are like one of an estimated 75 million owners of a digital camera, at some point in time, your camera will more than likely develop one or more problems and would be in need of digital camera repair. Common problems include cracked LCDs, broken battery doors, jammed lenses or board level problems.

There are a set of digital camera models however, that develop their own unique problems, all stemming back to a batch of defective CCDs that Sony produced and used in these camera models.

To start with, what is a CCD? A CCD is a Charged-Coupled Device, that "enables the transportation of analog signals through successive stages and are used as a form of memory or delaying samples of analog signals".

Now for that in English: In the digital camera world, CCDs are used by the camera to capture the image that is shown by the lens, translate it into a digital signal and send it along to the image processor to be converted and saved to the memory card.

What's the big deal with the faulty CCD? Well Sony produced a series of CCDs for various digital cameras between the years of 2003 and 2005, for at least 20 different models. And in higher heat and humidity conditions, the CCDs would begin to fail, producing some crazy looking images or causing a black screen to show on your camera (Before you starting thinking your camera has a bad CCD, PLEASE check and make sure your "display" button is not pressed and just shutting the LCD off).

So what does this mean for the consumer? Simple: If you own a camera that is covered under the Sony CCD recall, and your camera develops a problem as described above, you can generally send your camera to the manufacturer and get the CCD repaired for free. The largest affected manufacturers are Canon, Konica Minolta(now part of Sony) and Sony, but luckily for consumers, these manufacturers are standing behind their products and fixing their faulty CCDs. At one time the manufacturers were just replacing the cameras with new models, but lately it seems, they have gotten the CCDs fixed and are replacing them for you. Same camera, but you get a new, updated CCD and many more years of memories!

As Sony is the original sensor manufacturer for all of the other manufacturers' products listed (and given the vast array of products that they manufacture themselves) it should come as no great surprise that Sony has by far, the greatest number of affected products. This should not be taken as indicating any inherent deficiency in Sony products beyond the now discontinued sensors.

Don't throw your digital camera away if it has a bad CCD and it is covered under this recall, get it repaired for free! The best part about having the manufacturer repair your camera under this recall is that they will inspect, test, calibrate and update the camera as well as replacing the CCD with an updated version that will not fail as the first one did!

If your camera takes only solid black photos, or blurry pink/purple photos, call your manufacturer and ask them if the camera is on the CCD recall list today! If your camera is on the CCD recall list and you do not have this problem, YOU WILL in the future, so get it repaired now before the recall ends!

Outdoor Long Range Infrared Night Vision Cameras to Protect Your Home


When you hear something outside your home at night, and are trying to determine the cause, the automatic thing to do is usually to turn on lights and peek through the blinds. Unfortunately, this method of checking outside, albeit the most common, actually just lets whomever is outside see you. There is a much better method of being able to see exactly who is outside your home at night, even if it is completely pitch black. Using specially designed outdoor Infrared night vision security cameras, can provide you with a clear video feed of what is happening, so that you can safely watch your home and alert authorities if needed, without letting on your position to anyone who is outside.

Long Range Infrared night vision cameras employ infrared style LEDs or arrays that will illuminate the area in front of the camera with an invisible infrared light. This light is not visible to the human eye, but is visible to the image sensor of the camera. IR light will allow the camera to see in black and white during the nighttime hours, so that the camera can clearly see everything that is happening. Long range versions of these infrared night vision cameras can even deliver IR light that can be seen by the camera up to 100, 150 or 200 feet away from the camera. These cameras have more powerful IR LEDs for greater illumination, and often have lower light image sensors as well.

When selecting a long-range night vision security camera, it is important to understand that the range of the camera is rated by the distance under ideal conditions that the IR light will reflect back to the camera and provide a picture. At 72° F with 0% humidity, the rated distance will be the distance that the IR light will stop reflecting back to the camera. In order to deliver the best picture quality and clarity, it is highly recommended to keep the object being viewed between 60-80% of the maximum rated infrared range. This will help to compensate for changes in temperature and humidity and still deliver a good picture quality at night.

Another consideration to keep in mind when you are selecting a night vision camera, is the lens that will be used. Having a long range infrared camera will not really help you if the camera has a fixed lens that is a wide angle view. This is because even though the camera may be rated at 100' or more for IR light, that rating does not say anything about how large something will appear on the screen. With a wide angle lens at that distance, items on the screen will be very small and therefore almost impossible to distinguish. That is why many of the better quality Long-Range IR cameras will come with what is called a varifocal lens. These lenses have the ability to adjust the zoom and focus of the camera, allowing you to custom-tailor the width of view as desired to provide the best distinguishing characteristics.




At Platinum CCTV, our latest line of long range infrared night vision cameras deliver great quality video with 700TVL Sony CCD Image sensors, and all of them also have adjustable varifocal lenses to help deliver the best quality video for your home or business security camera system. Our CD-9361Outdoor Long Range Infrared Bullet cameras have up to 200' infrared night vision, and our CD-8361 Outdoor Armor Dome IR Security Cameras are a great choice for a smaller footprint dome installation.
